Lower lid blepharoplasty is performed with great variation in technique. Conventional lower lid blepharoplasty with anterior fat removal via the orbital septum has a potential lower lid malposition rate of 15% to 20%. Lower lid malposition and the stigma of obvious lower lid surgery have led plastic surgeons to continue to change their approach to lower lid rejuvenation. In recent years, some surgeons have come to rely on alternative procedures like laser resurfacing alone or in conjunction with transconjunctival fat removal and canthopexy in an effort to avoid such complications. The pinch blepharoplasty technique removes redundant skin without undermining. This allows for more controlled wound healing, predictable recovery, and potential for simultaneous laser resurfacing. The combination of pinch blepharoplasty with transconjunctival fat removal leaves the middle lamella intact and reduces the chance of scleral show or ectropion. The purpose of this series is to demonstrate that pinch excision of redundant lower eyelid skin can be safely performed and that it can be used with laser resurfacing and/or transconjunctival fat removal for optimal treatment of the aging eye. A retrospective review of 46 consecutive patients who underwent pinch blepharoplasty, either in isolation or with other periorbital procedures was performed. Follow-up was at least 4 months (range of 4-24 months). In addition, we performed a prospective study of 25 consecutive patients to quantify the amount of skin removed and evaluate results and complications. An average of 8 mm of skin was resected (range of 4-12 mm) with the pinch blepharoplasty technique. Of these patients, 5.6% also underwent transconjunctival blepharoplasty, laser resurfacing, and/or fat grafting of the nasojugal groove. Despite the addition of simultaneous laser resurfacing, we did not see an increase in lower lid malposition. Three of the 71 patients had temporary scleral show that resolved with lower lid massage. In total, only 4 patients had isolated pinch lower lid blepharoplasty. Twelve patients had orbicularis suspension and 15 had either canthopexy or canthoplasty. Five patients who had orbicularis suspension, canthopexy, or canthoplasty had periorbital edema. Two also had pronounced chemosis. Four patients had mild rounding of the lower lid. Pinch blepharoplasty is a versatile technique that produces consistent results. This study confirms that more skin from the lower lid can be resected than classically described. Pinch blepharoplasty can be performed safely in combination with other procedures to enhance lower lid appearance. The absence of skin undermining allows for safe simultaneous laser resurfacing. Preserving the middle lamella and supporting it when necessary allows one to resect significant amounts of lower lid skin without significant risk of scleral show, lower lid rounding, and ectropion. Patients with poor lid tone or laxity may benefit from supportive procedures such as the canthopexy or canthoplasty.
下睑整形术的技术差异很大。通过眶隔进行前脂肪去除的传统下睑整形术,下睑错位的潜在发生率为15%至20%。下睑错位以及明显的下睑手术痕迹,促使整形外科医生不断改变下睑年轻化的方法。近年来,一些外科医生开始依赖单独的激光表面重塑或联合经结膜脂肪去除和眦固定术等替代手术,以避免此类并发症。捏褶睑成形术技术可在不进行皮下分离的情况下去除多余皮肤。这使得伤口愈合更可控、恢复可预测,并且有同时进行激光表面重塑的可能性。捏褶睑成形术与经结膜脂肪去除相结合可使中间板层保持完整,并减少巩膜外露或睑外翻的几率。本系列研究的目的是证明可以安全地进行下睑多余皮肤的捏褶切除,并且它可与激光表面重塑和/或经结膜脂肪去除联合使用,以实现对衰老眼部的最佳治疗。对46例连续接受捏褶睑成形术(单独或与其他眶周手术联合)的患者进行了回顾性研究。随访时间至少为4个月(4至24个月)。此外,我们对25例连续患者进行了前瞻性研究,以量化切除的皮肤量并评估结果和并发症。使用捏褶睑成形术技术平均切除8毫米皮肤(范围为4至12毫米)。在这些患者中,5.6%还接受了经结膜睑成形术、激光表面重塑和/或鼻泪沟脂肪移植。尽管同时进行了激光表面重塑,但我们并未发现下睑错位增加。71例患者中有3例出现暂时性巩膜外露,通过下睑按摩得以缓解。总共只有4例患者接受了单纯的捏褶下睑睑成形术。12例患者进行了眼轮匝肌悬吊,15例进行了眦固定术或眦成形术。5例进行眼轮匝肌悬吊、眦固定术或眦成形术的患者出现眶周水肿。2例还伴有明显的球结膜水肿。4例患者下睑有轻度圆润。捏褶睑成形术是一种通用技术,能产生一致的效果。本研究证实,下睑切除的皮肤量可比传统描述的更多。捏褶睑成形术可与其他手术联合安全进行,以改善下睑外观。不进行皮下分离允许安全地同时进行激光表面重塑。保留中间板层并在必要时给予支撑,使得在不显著增加巩膜外露、下睑圆润和睑外翻风险的情况下,能够切除大量下睑皮肤。睑张力差或松弛的患者可能从眦固定术或眦成形术等支撑性手术中获益。
